Abstract
Copelatus oblitus Sharp, 1882 Source of material. The five instar II and five instar III larvae studied were reared ex ovo from adults collected at the following locality: Japan. Mantaburu, Yonaguni-cho, Yonaguni-jima Island, Okinawa Prefecture. 24°27’04.1”N 122°57’36.8”E, 13VI.2019; K. Watanabe leg. Diagnosis (instar III). The third instar of Copelatus oblitus can easily be distinguished from that of the other species studied in this paper by the following combination of characters: HL = 0.80 mm; L3 <2.00 mm; U <0.30 mm; head capsule ovate, not constricted at level of occipital region (Fig. 30), scale-like sculpticels present over frontoclypeus and parietale; anterior margin of frontoclypeus narrowly convex, extending mesally well below level of adnasalia (Fig. 30); adnasalia margined with short bluntly rounded teeth (Fig. 64); MP2/MP1> 1.50; GA/MP1> 1.50; 1.30 <LP2/LP1 <1.90; inner margin of stipes lacking a dorsal linear row of spinulae; profemur with less than 3 PV and 4 AV secondary setae; metafemur with less than 3 AV secondary setae; urogomphus composed of two urogomphomeres; U/HW <0.40; U/LAS <0.50; Oriental and Palaearctic. Description, instar II Body: Measurements and ratios aimed to characterize body shape are shown in Table 4. Head: Head capsule ovate, not constricted at level of occiput; anterior margin of frontoclypeus narrowly convex, extending mesally below level of adnasalia; scale-like sculpticels present over frontoclypeus and parietale; adnasalia margined with short bluntly rounded teeth (see Fig. 64); HL = 0.55–0.58 mm; A/MP = 1.39–1.51; MP/LP = 1.70–1.82; MP2/MP1 = 1.67–1.95; GA/MP1 = 1.85–2.32; LP2/LP1 = 1.56–1.89; MNL/MNW = 2.41–2.61. Thorax: L3 = 1.10–1.13 mm. Abdomen: LAS = 0.37–0.39 mm; LAS subconical, not constricted posteriorly at point of insertion of urogomphi. Urogomphus: U = 0.17–0.19 mm, composed of two urogomphomeres; U/HW = 0.26–0.29; U/LAS = 0.45–0.51. Chaetotaxy: Parietale with 3–5 temporal spines; position and number of secondary setae on legs are shown in Table 5. Description, instar III (Figs 30–33, 64). As second-instar larva except as follows: Body: Measurements and ratios aimed to characterize body shape are shown in Table 6. Head (Figs 30, 64): HL = 0.74–0.80 mm; A/MP = 1.50–1.60; MP/LP = 1.65–1.82; MP2/MP1 = 1.44–1.67; GA/MP1 = 1.59–1.83; LP2/LP1 = 1.31–1.47; MNL/MNW = 2.40–2.60. Thorax (Figs 32–33): L3 = 1.57–1.64 mm. Abdomen (Fig 31): LAS = 0.54–0.60 mm; U = 0.20–0.25 mm, U/HW = 0.22–0.27; U/LAS = 0.37–0.47. Chaetotaxy: Parietale with 3–4 temporal spines; position and number of secondary setae on legs are shown in Figs 32–33 and Table 7.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
